The only way i can bring up Oqueue is by /oqueue. Even when i do bring it up nothing loads or comes up. I have downloaded the latest version as well. Also mini icon on map is not showing

The minimap icon missing is something we are looking into. 

At the top center of the oQueue addon what does the version say? 

Also, when you say nothing comes up do you mean groups?

You probably are not connected to the mesh. Check your connection in the bottom right hand corner of the find premade tab. To increase your connection you can use the find mesh button to recieve battle net friends, you can also check that on the setup tab you have "Auto join oQ general" checked.
